Characterization of the complete mitochondrial genome of a stonefly species, (Plecoptera: Pelidae).

We have sequenced and analyzed complete mitochondrial genome (mitogenomes) of the , the third mitochondrial genome in the genus which belongs to the family Pelidae in this paper. The mitogenome of  is circular with the length of 16,077 bp, which possessed 37 genes and a control region like other stonefly. The A + T content of the whole mitogenome was 67.1%. All PCGs were 11,217 bp in length, accounting for 65.3% of the content of A + T. The A + T content of lrRNA and srRNA were 72.3% and 66.4%. The highest A + T content was in the control region (76.2%). There are 15 gene overlaps and 9 gene intergenic spacers in this mitochondrial genome. In addition, we performed phylogenetic analysis by using the Bayesian (BI) and Maximum Likelihood (ML) methods based on the concatenated data set of PCGs from 11 species in Pelidae and two species in Styloperlidae (outgroups). The clade + was a sister group to , which is consistent with the traditional morphological classification.
